Product Description

FEM standard double girder overehad crane is one of the most common overhead cranes, also known as EOT crane. The crane steel structure is reasonably designed, optimized, in line with regulations and standards, and meets the requirements of strength, rigidity and stability. During the design process, the on-site working environment is fully considered; the steel structure design also takes into account the convenience and possibility of manufacturing, inspection, transportation, installation and maintenance. Under the condition of meeting the needs and existing specifications and standards, the weight of the steel structure is minimized through optimization design methods such as limited edge analysis. The traveling bridge runs two parallel double-ended beam runways across the gap between two rails. It is powered by electricity and the motion control is achieved through the operator's cab or the suspension control device together with the overhead crane. Double girder overhead cranes are widely used in warehouses, workshops, material yards, and can help unload or relocate heavy objects. Usually, overhead cranes can not only achieve traveling movement in two directions, but also easily raise or lower heavy objects.

Characteristics

Runway Rails: Tracks installed along the length of the building or on freestanding columns that guide the end trucks, allowing horizontal travel of the entire crane structure across the workspace.

Control System: The interface for the crane operator, allowing control over lifting, lowering, trolley movement, and bridge travel. Options include pendant controls, wireless remotes, or a cabin control for large or complex applications.

Cabin (Optional): For cranes with a dedicated operator cabin, the cabin allows operators to directly view the load and manage precise movements, often used in applications requiring detailed handling or continuous operation.
Double Girders: Two horizontal beams spanning the width of the crane and carrying the hoist and trolley. These girders support heavy loads, distributing weight evenly and providing enhanced stability and lifting height.

End Trucks: Located at both ends of the girders, the end trucks house wheels that allow the crane to move along runway rails. These ensure smooth and stable travel of the crane across the workspace.

Trolley: The mechanism that travels along the top or bottom of the girders and carries the hoist. The trolley enables lateral movement along the crane’s span, providing precise positioning of the load.

Advantages

1 Precision and Reliability: Advanced control systems ensure accurate, safe, and reliable operation.
2 Space Utilization: Compact design allows for efficient use of space, even in facilities with height restrictions.
3 Cost Efficiency: Despite the high initial investment, the efficiency and low maintenance costs provide long-term savings.
4 Versatility: Suitable for a wide range of applications across different industries.
5 Enhanced Safety: Extensive safety features protect operators and materials, reducing the risk of accidents.

Application

1 Manufacturing Plants: Handling heavy components, machinery, and finished products.
2 Steel Mills: Transporting large steel products, raw materials, and heavy equipment.
3 Shipyards: Moving ship parts, engines, and heavy machinery.
4 Automotive Industry: Handling car parts, assemblies, and heavy molds.
5 Construction Sites: Transporting heavy construction materials and equipment.
